dual boot two hard drives

view story

http://askubuntu.com – I have two separate ssd drives on my computer. I would like to be able to have an option of dual boot in the grub menu at start up. At present ubunf8tu is the boot. My option to boot into openelect is two restart, and quickly select ctrl + f8 combination at start up. This allows me to select the drive from the bios menu at start up. Is this possible, how? Any help is valued. /dev/sda1 ubuntu 12.04 lts /dev/sdb1 openelect (HowTos)
